T o all whom z' may concern.'

erated. and atripping device adapted'to ne Be it known that I, Grs'rave B. linien-ion, a citizen of the United States, residing at lliilwaukee, in the count-y of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Electric Switches, of which the following a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of-this specification'. v

My invention lrelates to improvements in electric switches, andmore particularly to those adapt-ed to becontrolled from a'4 distance.

The various objects and advantages of my invention will behereinafter fully and clearly set forth. v

, According to the preferred form of my invention, I provide an lautopiaticallv operated switch adapted to be controlled from a distance, with mechanical means for maintaining the same closed after being opactuated.

For the purpose of more fully disclosing the characteristic features of my invention,

Ishall describe the device illustrated in the accompanying drawing, which embodies my invention in one forni.

Of course, my invention is capable otvarious modiications.

The views in the accompanying drawings are as follows:

Figure 1 is a side elevation of 'the de vice, parts thereof being shown in section; Fig. :2 is 'an enlarged view of part of Fig. 1, parts thereof being shown in section;'Fig. 5 is an Fig.

enlarged sectional view taken on'line 3--3, 1; Fig. at is an enlarged sectional view taken on line lL-f1, Fig. 2; Fig. 5 is a. sectional view taken on line 5-5. Fig. 2; Fig. t3 is a bottom plan view' 'of the tripping mag net; frame., and Fig. 7 is a 'perspective view et f 'of-the device. n

h6 switch, 0 which I have shown for the purpose of illustration, is of a conventional type. Briefly described, this contactor comprises a magnet frame 8 suitably secured to an insulating panel or base 9. Mounted inthe frame is an electromagnet 10, having a movable plunger 11 connected by a pin 12 to a switch or contact arm 13 pivted to the frame 8. vThe arm 13 carries a main Contact 14: and an arcing contact 15, adapted to engage alaminated main contact 16 land a pivoted arcing contact 17, respectively, said last mentioned 4contacts provided for disrupt-ing the arcs formed between the arcing contacts. ,As before stated, this contactor is merely shownfor the purpose of illustration, andv it should be understood4 that the same may bev of any preferred type.

I shall now describe those parts which more particularly pertain-to my invention.

Secured to the insulating base 9,' in any desirable manner, is frame 20. As shown, they frame Q0 is provided with an upwardly extending portion Q1 secured to the insulating base between -the same and the magnet traine 8 by a bolt 22. At its lower end the 'trame 20 is provided with a hollow rectangular portion adapted t-o receive an electroniagnet. which will be hereinafter referred to as a tripping magnet. The magnet 23 is provided with a stationary core 26,

"J andra movable plunger 27. The stationary core passes througha suitable aperture in the bottom of the frame E20, and is provided at. its end' with an annular lla-nge, which is secured by screws 28 to the frame 20. It ywill thus be seen that the core 2G serves to retain the magnet 23 in the frame. The magnet Q3 is additionally securedin the frame by means of set screws 24 provided with jam' nuts 25. At its upper end the rec.- tangular portion'of the frame QO-is provided with an upwardly extending lug 29, tor the purpose hereinafter explained. Passing through suitable ears 30, provided at the upper end of the frame 20, is apin 31, retained in place by cot-ter pins 32. Fulcrunied on 'the pinA 31 is a bifurcated weighted lever Y33. The`-bifurcations of the lever 33 have. upwardly extending projections 34 and 3 5, suitably spaced, and pro vided forthe purpose hereinafter set forth.

liulcrumed on the pin 31, between the bibeing supported by the magnet frame. A'. blow-out magnet 18 having --pole pieces 19 is furcations of the weighted lever, is a substantially U-shaped member 36, having i. downwardlyextending lug 37 adapted to engagethe lug- 29 on the frame 20. The

' member 36 is best illustratedin Fig. 7. The upper ends of the legs of the member 36 are provided -with lateral extensions 38, through which passesa pin 39. The'pin 39 also passestlirough a pair of links 40, which are* maintained thereon by cotter pins 41. The portions 38 of the member 36 are disposed between the Aprojections 34 and 35 of the weighted lever, and are adapted to be engaged thereby and the member 36 moved in one direction or the other as the weighted lever is' moved. The upper ends of the links40 are fulcrumedon the pin 12, which connects the switch arm 13 to the plunger of l'. its operating solenoid. With this arrange- 20 ment it will, be'seen that the links and the member 36 forma toggle connection between the switch arm 13 and the Vframe 20.

Thefunction of the lug 37 will now be explained.

^ soon as the switch 13 is closed and locked,

its operating winding may be denergized. To open the switch it is necessary to breakthe toggle.4

The function of the weighted levei` will now be explained.

Inasmuch as the weight is on the forward' end of this lever, it is apparent that said weight normally tends to move said lever in a direction to cause the projections 34,. thereon to' engage the extensions 38 on the upper end of the member 36. Hence, when the toggle is straightened upon the closure of switch 13, the weight tends to throw said toggle past the center to lock said switch in closed position. The rear end of the weighted lever is connected by a link 42 to the plunger` 27 of the tripping magnet 23. Hence, when said magnet is energized, the weighted lever is rocked to cause' theprojections 35 thereon to engage the extensions on the member 36 and move said member to break the toggle. This causes the switch 13 to open. Inasinuch as the projections on the weighted .lever are a considerable distance apart, the projections 3,5 will'not be brought into engagement with the toggle until the weighted le\.'er has been.l rocked some little distance-by its operating inagnet. Tliusthe weighted lei-'er acquires considerable momentum before engaging the toggle, and consequently imparts a hammer hlnw tlwint'n which 'miieklw breaks: said tonfgle. VVit-h this arrangement a comparatively small tripping magnet maybe employed.'

As soon as the switch 13 is again closed, the weighted lever will cause the toggle to set to lock `the switch closed. l v

It will thus be seen that by merely energizing the solenoid 10 for a short time the switch 13 4will be closed andthen the toggle will maintain it in closed position. magnet. l0 may then be denergized.- When desired to open the switch, it is only lnecessary toenergize" the tripping magnet momentarily to operate the weighted lever to break the toggle.

Having thus described my invention, what The I claim asnew and desire to secure by Letters A:Pa-tent, is

1..In combination, a pivoted switch, an

operating solenoid therefor havin a movable plunger connected to said switch', tog gle links automatically set upon closure 'of said switch to mechanically lock the same lin closed position, said toggle links when setbeing substantially in alinement with the plunger of said solenoid and a single device tending to set said llinks and operable toimpart a hammer-like blow thereto.
